Drill hole name
Columnar section showing coal beds (black) penetrated by drill hole. Down-hole depths are shown at 100-ft intervals and lableled at 500-ft intervals. Thickness of coal is shown in feet on left side of column. Thickness of bracketed interval represents total coal in an interval that also contains partings; the partings are thinner than the adjacent coal seams and are not included in the recorded coal thickness.
Geophysical logs—Gamma ray (GR) or spontaneous potential (SP) logs are shown to the left of the columnar section; resistivity log (RES) is shown to the right of the columnar section. Resistivity logs are plotted using a logarithmic scale.
